Joomdle system check fails

Sorry for the new post but i can't reply to my previous
Here : www.joomdle.com/forum/installation/11843...incorrect-joomla-url

So i still got the system check issue, but the message is not the same anymore...
Now i got : "An un attended error occured : 404 : unknown error. "
Any idea ?

If it can help : i can't get logged in moodle through my website, even if the settngs seems to be correct in moodle and joomla :
- User exists in both site,
- Joomdle on moodle is the authentification method.
- But the Moodles users created via joomdle have no prename nor name set in Moodle.
I really need your help, pls Antonio.
Thanks .

404 means the page cannot be found.

- What have you changed which has caused the message to change?
- What are the URLs that you are entering in both Joomla and Moodle. You can use mydomain.com as an example if you do not wish to share the actual.

You need to enable debugging in Moodle to get more info about the 404 error.
